unrouted vlans and asa

how do unrouted vlans on a cisco switch get to my ASA. Shouldn't they not be leaving that vlan. I am getting a bunch of pings hitting my firewall from unrouted vlans that are internal

    If the ASA does not have interfaces in those VLANs and you are sure there are no layer 3 interfaces on any routing capable device then you have a faulty switch/trunking setup somewhere. Most likely though is a misconfigured router with layer3 ports/SVIs in the problem vlans and the ASA is the default route.
    We responded to the Year 2000 issue with "Y2K" solutions...isn't this the kind of thinking that got us into trouble in the first place?
